本文阐述了都尔对大豆田禾本科杂草、阔叶杂草的防除效果，表明2250mL／hm2和3000mL／hm2两种剂量的都尔对禾本科杂草防除效果在98％以上，对苋菜、灰菜防效在47％以上，而对其它阔叶杂草则基本无防效。建议在禾本科杂草基数高的田块，使用3000mL/hm2的剂量；在禾本科杂草基数低的田块，使用2250mL／hm2的剂量；在以阔叶杂草为主的田块，应与氯嘧磺隆混用。
This paper describes the control effect of Dole on grass weeds and broad-leaved weeds in soybean field, indicating that the control effects of both dosages of 2250mL / hm2 and 3000mL / hm2 on grass weeds are over 98% The efficacy of vegetables is over 47%, while the other broad-leaved weeds are basically non-effective. It is suggested that the dosage of 3000mL / hm2 should be used in the fields with high base of grass weeds; the dosage of 2250mL / hm2 should be used in the fields with low base of grass weeds; Mix with chlorimuron.
